天赢居：反弹升级，关键看3888和3918定方向

Core Viewpoint - The market experienced a significant shift on December 17, with a resurgence in technology hardware, transforming a previously weak rebound structure into a more robust one. The performance around the levels of 3888 and 3918 will determine whether this rebound is a continuation or the start of a strong reversal at the 21-day mark [1]. Monthly Analysis - After reaching the monthly golden target of 4018, the focus is on avoiding the 55-day washout cycle while monitoring the direction of the 21-day and 34-day nodes. The current pullback does not alter the overall bullish framework, but the key task is to use time to create space and digest the top positions for a higher probability attack in the future [2]. Weekly Analysis - The current adjustment is characterized as a washout phase following a full rise over 89 weeks. The five-week washout has found support at the 21-week moving average of 3847, indicating a potential for a rebound, although it remains in the washout phase below the 8-week moving average of 3916 [3]. Daily Analysis - The formation of a "poison spider" pattern near the 3895 level on December 15 indicated caution, leading to a confirmed breakdown on December 16 as the index fell below the 89-day moving average of 3865 and the trendline support at 3855. On December 17, a rebound occurred from the previous low of 3816, reaching the 89-day moving average of 3869 and the 21-day moving average of 3883, but it remains within a downward channel [4]. - The intersection at 3888 serves as the upper boundary of the downward channel, while the 55-day moving average at 3918 represents the top of the previous 16-day trading range. The area below indicates a continuation of the downtrend, while the area above is critical for determining if the rebound can escalate to a higher level [4][5]. Hourly Analysis - The midday surge in technology hardware on December 17 led to a renewed bullish momentum in the hourly MACD/KDJ indicators, marking a shift from a mere rebound to a more pronounced rally. However, multiple moving averages and resistance zones above suggest that the most realistic short-term path involves oscillating within the 3888-3918 range before deciding on further upward movement [7]. Time Cycle Analysis - The A-wave decline from 4034 to the 89-day moving average took 7 days, mirroring the C-wave decline from the December 8 high of 3936 to December 17. The 21-day and 34-day nodes are critical for increasing the probability of success, with the midday signs on December 17 indicating potential for a strong rebound if key resistance levels at 3888 and 3918 are held and accompanied by increased volume [8].
